I’m not an expert and as such can’t really analyze it fully. But what I took away is that it aimed to test a part of new theory by with a very narrow measurement, using early-universe density oscillations. They left dark matter out of the equation with the new model, and it was a smashing success if you’re willing to overlook that it requires the universe to be a completely different age than it is… In short, this is shenanigans.
edit2: It also presumes the “tired light theory” is true. Tired light is the flat earth of astrophysics/cosmology. Yeah, there are contrarian knuckleheads in every discipline.
Don’t get too excited, this is a pretty fringe theory that doesn’t really have experimental evidence. They were able to make some observations fit with their theory without dark matter yes, but not all of them. The tired light part in particular has a lot of contradictions with observation that they don’t explain.
I’m a workshop kind of guy that enjoys space documentaries. For my part, I see “dark matter” as a known hole in our current understanding of cosmology, and I bet when we figure out how it does actually work it’ll lead to some really cool TV shows.
It’s not that dark matter was the only theory, there are also different theories based on modified newtonian dynamics (MOND), these aren’t any better than dark matter though, maybe even worse theories.
This stuff is way, way over my head. And probably most of humanity right now. In this moment I can feel some envy and admiration towards whoever is around to understand the great breakthroughs we may one day have on this matter.
Coles notes: scientists made calculations on the universe and it didn’t make sense because the math says there should be more mass and energy than what they know exists. So they called the missing mass dark matter and the missing energy, dark energy.
Now some guy in Ottawa figured out better math that doesn’t need the “dark” stuff to make the math make sense.
My understanding of dark energy is a little different. As I understand it, we figured gravity pulls things together, right? So everything should be kinda slowly falling back together from the big bang. It was theorized to end in a ‘big crunch’ where the universe collapses back and then explodes again in a cycle.
Only when they tried to measure how fast distant objects were moving relative to us, they found that things were still moving away from each other. More than that, the farther away things were, the faster they were moving. Meaning distant objects were accelerating.
Acceleration requires energy, but we don’t know the mechanism behind this, or where the energy comes from. Hence, dark energy.
kinda, dark energy is the unknown explanation for the expansion of the universe. Once we understand it enough to know what it is responsible for it’ll no longer be dark.
You humans and your primitive knowledge. The rest of the universe knows that this dark energy you haven’t found out yet is called Mana and allows miracles to be made. /S
Just to be clear, there are lots and lots of different observations that are ; it’s not just a single term in “the math”. Furthermore, the hypothesis presented in this article is not “better math” because it does not do as good a job as dark matter in explaining all of these observations.
um i browsed it for nearly two minutes and at the very top of the page there was clearly a chart. i didn’t understand it but obviously we can conclude that it is based on scientific science
